Do you have the model with circuit breakers below glove box? They reset themselves when key turned off, but if still a short, or excess draw they will trip again. After while they get pretty weak and may trip constantly.

likely your blower motor. but take connector off at blower, key on, htr on high. should have power at connector. check with a test light. If power is present, its your blower. If no power, and fuse is good, it's a wiring issue or your heater blower switch on the dash.

Did you check the fuses in the fuse box? In the engine compartment. For windows. Take off the driver/passenger side interior door panel. Turn ignition to the on position, don not start car. Use a volt meter or a electrical probe. Check for current to controls. Then check for current at the connectors. You can do the same for the heater. But first check fuses. Also check if there are any inline fuseable links burnt out to the units.

I had the same problem a few years ago on a converted '92 Ram B250 van. Turned out to be a blown fusible link in the engine compartment, under the hood, right next to / behind the brake master cylinder. These links were used instead of fuses up until '92, so it is likely the problem you are having as well.
